I tried to set the Min value of slider to 1 and Max value to 2. But after I execute it,the slider doesn't appear in GUI and matlab return an error: Warning: slider control can not have a Value outside of Min/Max range Control will not be rendered until all of its parameter values are valid
Anyone know how to solve this problem?

What 'Value' are you initializing the slider to? The default is 0 for a slider no matter what the Min and Max are.

Yes, no problem, You just have to ensure that you initialize the Value parameter so that it is in that range.
uicontrol('Style','slider','Min',1,'Max',2,'Value',1)

Thanks a lot. What does 'Value' mean?
If i want the Min to be 2, I have to change 'Value' to 2 as well?

Although the correct answer is already given by Walter Roberson, I want to add something more.
I also faced the same problem and solved it using Property Inspector of Slider.
For example, my lower limit was 0.2 and the upper limit was 0.5. So, in Property Inspector of Slider, a row with name Value is there (2nd last). By default, its value is always zero but my minimum value was 0.2 so it was showing the error. To avoid error I put Value = 0.35. As shown in Fig.
Remember your value in Value row should be equal to or more than your minimum value.

To create sliders using the UICONTROL function, specify the value of the slider at its time of creation to be greater than or equal to the 'Min' value. The following example code will work as expected:
